feat: Update docker file (#1225)

### Summary
The previous Alpine-based image was unreliable for some IDE dev
containers. This change moves to Debian Bookworm slim, adds
ca-certificates so install-idl (git over HTTPS) works inside the image,
and defers npm to after the container starts so a failed install no
longer blocks the dev container from coming up. Image size may grow
slightly, though still in acceptable range.

### Changes
- Dev containers / IDE compatibility: Base image and layout adjusted so
dev containers work consistently across environments that struggled with
the old image.
- ca-certificates + git: Installed via apt-get so TLS verification
succeeds when install-idl runs in-container.
- Dev stage: No longer runs npm ci / dependency install as part of the
image build; npm can be run after start, avoiding failed installs
blocking container startup.
- Build: Removed the extra npm run build step before build-standalone
(standalone path is sufficient).
- Docker ENV: Updated to the modern ENV KEY=value form to clear the old
ENV format warning.


### Testing
- Open the repo in a dev container in the IDEs that previously failed;
confirm the container starts even before npm install / npm ci.
- Check size change:

/>
- After start, run npm ci (or your usual install) and confirm npm run
install-idl completes without TLS/git errors.
- Docker build default/production target and smoke-test the running app.
- Confirm Docker build logs no longer show the ENV deprecation/warning
(screenshot for old warning):
